How much soil do the standard beds take?

FORMULA:
Bed Length x Bed Width x Bed Height = m3 of Required Soil
1m3 of Soil = 1000 Litres
EXAMPLE 1:
1.2m (L) x 0.4m (W) x 0.3m (H) = 0.144m3 of required soil
0.144m3 of Soil = 144 Litres
EXAMPLE 2:
0.9m (L) x 0.9m (W) x 0.4m (H) = 0.324m3 of required soil
0.324m3 of Soil = 324 Litres
EXAMPLE 3:
2.2m (L) x 1.3m (W) x 0.4m (H) = 1.144m3 of required soil
1.144m3 of Soil = 1144 Litres
